💡 A proper RFC 4180 parser — handles quoted fields, commas and line breaks inside quotes, and escaped quotes. With "first row is a header" on, you get an array of objects; off, an array of arrays. Everything runs in your browser.

Қалай жұмыс істейді

CSV looks simple but is full of edge cases — quoted fields, commas inside quotes, line breaks inside cells. This uses a proper RFC 4180 parser so those all work, entirely in your browser.

1
You paste CSV or drop a file
The delimiter (comma, semicolon, tab, or pipe) is auto-detected, or you can set it manually. Nothing is uploaded.
2
It's parsed correctly
Quoted fields, escaped quotes (""), and delimiters/newlines inside quotes are all handled per the CSV spec.
3
You choose the shape
With a header row, each line becomes an object keyed by the headers; without, an array of arrays. Optionally convert numbers and booleans to real types.
